Sashco 16210 Slab Concrete Crack Repair Sealant, 10.5 oz Cartridge, Gray (Pack of 1)

Perfect for my needs. Nice and thick and gritty like concrete and smooths down perfectly. Does not run down vertical curbs so I can replace and secure chunks out of my driveway curb. Will buy again.

Applies smoothly. Remains somewhat flexible after it cures. Matches well to the cement. I applied this between my new driveway and my 30 year old garage floor. It gives a finished appearance and keeps water out of the joint.

I used this before to fill the cracks and lasted. I ordered 6 tubes to fill the cracks on my detached garage floor prior to adding 3" of new cement on top. Unfortunately, the floor had a lot of settlement under the floor and it needed to be jackhammered out and repoured. I had to return the tubes.

I've tried a handful of different similar products. I like the color and texture of this the best. It's the only one that actually matches the color of my driveway. Other review claims are true - it does take a LONG time (days) for this stuff to solidify. However, I'm putting it in driveway cracks, where it isn't touched, so it doesn't matter that it takes a while to dry. It rained the day after I applied it, but the rain didn't seem to negatively impact the stuff. Overall, it's the best one I've tried. I just ordered a 2nd tube to fill cracks on my back patio.

I just used this for the second time in about 5 years on 2 different projects. It's amazing. It absolutely seals whatever you put it on. And it lasts for years. It's also easy to work with and easy to clean up.The only downside is that it takes about 24 hours to develop a skin and about 30 days to fully cure to a rubber like finished product. So you'll need to make sure it's reasonably well protected for 30 days while it cures.

I installed the product into a 3/8" crack in my concrete sidewalk. At first, I was impressed with how easy it was to install. It also cleans up nice and looks great...BUT - It is going on 4 days now and it has not hardened at all. You can put your finger right down through it.UPDATE: It took a month or so to stop being mush and is actually holding up pretty well.

Why did you pick this product vs others?:Great product hands down! Live in CO and have to keep up my driveway every year filling in those stubborn joint expansion cracks not to mention the nuance of removing the old sealant. This product has changed the game and the yearly routine is a thing of the past.

Works great to fill cracks in driveway. Recommend you cut the nozzle on angle and heat end tip to flatten out
